What is Unicode, UTF-8, UTF-16?
... data types: How are they encoded in the programming language? If they are raw bytes, the minute you try to output non-ASCII characters, you may run into a few problems. Also, even if the character type is based on a UTF, that doesn't mean the strings are proper UTF. They may allow byte sequences th...
Regular expression for floating point numbers
...ping can get very confusing. If the language you are working with supports raw strings, then you should use those to cut down on the number of backslashes, but not all languages do (most notably: Java). Fortunately, there's an alternative that will work some of the time:

When should I use C++14 automatic return type deduction?
... work.
As a real-world example, I was asked to change a module from using raw pointers everywhere to smart pointers. Fixing the unit tests was more painful than the actual code.
While there are other ways this could be handled, the use of auto return types seems like a good fit.

How do I discover memory usage of my application in Android?
...system to this point.
Going lower-level, you can use the Debug API to get raw kernel-level information about memory usage: android.os.Debug.MemoryInfo
Note starting with 2.0 there is also an API, ActivityManager.getProcessMemoryInfo, to get this information about another process: ActivityManager.g...
What's the right way to pass form element state to sibling/parent elements?
...n your situation.
If the app is a simple Markdown converter, C1 being the raw input and C2 being the HTML output, it's OK to let C1 trigger a setState in P, but some might argue this is not the recommended way to do it.
However, if the app is a todo list, C1 being the input for creating a new todo...
Why are joins bad when considering scalability?
...atabase used well. There are a number of scalability-friendly ways to take raw joins and make them much faster:
Join on a surrogate key (autonumer/identity column) rather than a natural key. This means smaller (and therefore faster) comparisons during the join operation
Indexes

Something like Process Monitor from SysInternals might give you a clue if the pronblem is that creating the DLL file is failing...
